Block Cipher Modes Of Operation

---

Please read Further Informations before using the provided code!

---

Description

The Block Cipher Modes of Operation belongs to the group of symmetric cryptography.

They can be used to encrypt data with a key and, depending on the mode, also with other parameters.

Example Implementation

#Encrpytion and decryption using CBC
from encryption_modes import cbc_encryption
from decryption_modes import cbc_decryption
from Essentials.converter import hex_to_ascii

encrypted = cbc_encryption("Plaintext", "Key", 0, 3)

print(encrypted)
print(hex_to_ascii(encrypted))

decrypted = cbc_decryption(
    hex_to_ascii(encrypted), "Key", 0, 3, True
)

print(decrypted)

-------------- CONSOLE OUTPUT ---------------
    >> 1B0918390215171F18
    >> �	�9�����
    >> Plaintext

Further information

This is just an implementation of the Block Cipher Modes of Operation.

Do not under any circumstances use this for any encryption of actual important information nor vulnerable data nor send or stored data in general!

The provided methods do not guarantee a safe and flawless encryption of the data and are therefore meant for experimental and learning purposes only!

Please use other encryption librarys with proven correctness for encrypting youre data!

Never roll your own crypto
